the Mountain Guns from S&W usually have the shorter barrels, rounded butts, and are a little lighter in weight. The intent is to keep such a gun to minimum dimensions and weight to those who work, hike, or camp in the mountains of the west, where elevation makes the air rarer in oxygen content.

My L-frame, 7-shot Mtn Gun weighs exactly the same as a K-frame, 6-shot S&W model 19. That makes it a total joy to carry and it can handle a steady run of full-house magnums without any problems - something the 19 is known to have problems with.

Your .44 Mag is essentially the same thing, just in a more powerful package.
